Sodium Chloride → HCID 54145573, compound

Participants

Reaction Steps

To a mixture of 1.08 g (3.1 mmol) of 4-[(3-chloro-4-fluorophenyl)amino]-7-methoxy-6-amino-quinoline-3-carbonitrile and 1.7 ml (9.7 mmol) of Hunig's base in 30 ml of dry THF at 0° C., with stirring, was added a THF solution containing 1.99 g (9.3 mmol) of 4-bromo crotonyl chloride dropwise. The mixture was stirred for additional 0.5 hour at 0° C. under nitrogen. 50 ml of saturated sodium chloride solution was introduced to the reaction mixture, then it was extracted with ethyl acetate. The ethyl acetate solution was separated and dried over sodium sulfate and then it was added to 31 ml of dimethyl amine solution (2.0 M in THF) at 0° C. dropwise. After addition, the solution was stirred for another hour at room temperature. The mixture was poured into diluted sodium bicarbonate solution . The organic layer was separated and the residue was chromatographed to give 0.86 grams of white solid: mass spectrum (electrospray, m/e).
